This chapter focuses on the emotional virtue of gratitude in society and education. First, it explores major understandings of gratitude prevalent in philosophy and psychology that elaborate what gratitude is, and why it is called for. The practices encouraged for cultivating feelings of gratitude by psychologists and educators will also be discussed. Then the chapter will turn to critical views of gratitude that question its moral value, its psychological utility, and its place in education. While teaching feelings of gratitude in the classroom may not necessarily be harmful, there are risks and challenges that should not be overlooked by educators interested in the moral and social development of their students.
